JOSHUA PIERPONT, LA HARPE, ILLINOIS, ASSIGNOB TO HIMSELF AND SIDNEY S. TU'ITLE, OF SAME PLACE.A

IMPROVEMENT IN DEVICES FOR SECURING SHOVELS AND PLOWSHARES T0 STANDARDS.

Specification forming part of Letters Patent No. 99,702, dated February 8, 1870.

To a/ZZ whom it may concern:

Be it known that I, JOSHUA PIERPONT, of La Harpe, county of Hancock, and State of Illinois, have invented a new and Improved Mode of Fastening Shovels or Plows to Uprights or Standards; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The invention relates to an improvement in the mode of attaching or fastening shovelsor plows to standards; and it consists of a castiron or other metal block, and wrought-iron or other metal ring, and a cast-iron or other metal thimble in such combination as to effect the object sought, and combines simplicity, utility, and durability, as hereinafter described.

Figure l is a side view of my improvement in shovel-fastenings in proper and combined position, showing the manner in which the shovel is held to the standard. Fig. 2 is a view of the block, ring, and thimble separately, showing their form and their adaptability to a successful combination.

The drawings represent a cultivator-standard, A, shovel-block C, shovel B, ring D, and thimble E. The shovel-block C is made concave on one side, to t the round standard A.

On the opposite side are two flat places withV rivet-holes therein, where the shovel B is riveted. On the outside of the block C, across the center, isa recess to fit and admit the ring D between the shovel B and theblock C. The ring Dis of wrought-iron, and fiat on its inner surface, the more eiiectually to iit the recess in the block C, and made round on its outer surface, to be more readily welded and leave or l form a round neck or shank, upon which a thread is cut and a nut iitted. rIhe thimble E is made bell-shaped, and its large end is made in a concave-circle shape, two ways, at right angles. The larger concaves are lfor the purpose of iitting upon the round standard A when placed in position over the shank of the ring D. The smaller concaves are for the purpose of preventing the thimble E from pressing upon the ring D when placed in position, and forced down upon the standard A with the nut. The thimble E is cast hollow,wit h a hole through the small end to admit the shank of the ring D. These parts are used properly by placing the ring D around and in the recess in the block C, and placing the thimble E upon the shank of the ring D, and inserting the standard A between these parts, the block C being upon the opposite side of the ring D upon its shank, upon which the thimble E is then placed, and the nut turned down until the thimble E presses upon the standard A, and the parts are all held rm.

By loosening the nut ou the ring D in Fig.

1, the shovel can be raised or lowered'to plow shallow or deep, and can be turned to throw dirt to or from the row of plants, and can be quickly and rmly fastened by Ithis device iny any desired position.

The standard A can be made smaller and lighter by this device, as no holes need be bored through it, thus weakening it, to fasten the shovel B thereon with bolts, as is the usual custom.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, iss Theiron or metal ring D,with shank, thread, and nut, or their equivalents, in connection and combination with the iron or metal thimble E, constructedv and operated :as and for the purpose herein described. y

The above specification of my invention signed by me this 9th day of July, 1869.

JOSHUA PIER-PONT.
